' v Application filed July 8, 1901.

To all whom; it may Gflwerni Be it known that I, THOMASJfBAIN, a cii i-..

zen of the United States, residing at Cairo,

' in the county of Alexander and State of Illinois, have invented a newand useful Electric Battery, of which thefollowing is a specification. i

This invention relates to electric batteries; and the objectof the present improvement is to so construct the parts of the cell that the liquid contents will be prevented from running or boiling over the upper edge of the jar by locating the elements wholly within the confines of the jar and avoid suspending'them' from the upper edge of the latter, and also'to have-the elements easily separable, so that they can be cleaned and readily placed in and withdrawn from the jar. Y

- The invention consistsin the'construction and arrangement of the severalparts, which will be more fully hereinafter described and claimed.

Figure l is a sectional view of a jar, showing the improved battery elements arranged therein and illustrated in side elevation. Fig. 2 is a transverse sectional View of the battery elements. Fig. 3 is a perspective view of the battery elements.

Similar numerals of reference are employed to indicate corresponding parts inthe several views.

The numeral 1 designates a jar of the usual or any preferred form. The elements are placed Within the said jar and comprise a lower copper cone 2, which forms a base-rest on the bottom of the jar, the said cone hav-' ing one of the joint members extended to form an inclosing roll or sleeve 3 on the inside to provide means of elongated securement of a wireor electrode l, of copper, which is directed upwardly through the jar and out over the upper edge of the latter for jointure with an electrical connection in the usual manner to arrange the cells in series or in parallel or, in the use of a single cell, for the attachment of a wire for the utilization of one pole of the battery for practical purposes. The extended attachment of the wire 4, as set fortlu insures a more direotand effi swarm. 57,509. (No model.)

upwardly over the stem, and to the upper end of thelatter a zinc element 10 is secured and formed with a series of radiating horizonland is thus held in place. The upper-end 6 tally-disposed wings 11 with radial interspaces 12 between them. Thewings are centrallydipped or depressed, so as to maintain operative relation to the fluid in the jar for a greater length of time in the event that said liquid becomes low, and by providing the interspaces between the wings the operation of the liquid on the zinc will be more effective,

as a greater surface in the aggregatewill be I exposed to the liquid than if the said zinc element was solid and simply presented the upper and lower faces and peripheral edge. The upper surfaces of the wings are formed with downwardly and outwardly inclined recesses 13, which will cause the liquid to more readily run off or free itself from the zinc when lifting the latter from the said liquid in the operation of separating the parts.

The liquid used in the present cell will be preferably that used in the ordinary gravitycell, though thisis not essential, as it is ob- .vious that negative and positive elements of the same form and arrangement as those particularly described as being composed of copper and zinc could be made of other'electric ally cooperating materials. Rising from the center of the element 10 is a binding-post 14,

for attachment of a connecting-wire or the notch 5 at the lower edge of the said cone,

nothing to lead the liquid upwardly over the edgeof the jar, and a cleanly cell is thereby produced. Furthermore, the parts of the battery can be easily separated for cleaning and are readilyassembled in the jar, the cone being first positioned and the zinc and stem afterward applied thereover.

Having thus described the invention, what is claimed as new is 1. A battery comprising a jar for containing an electrolyte, a lower conical element, and an upper element having a depending stem of non-conducting material provided with a lower hood of conducting material to removably fit over the upper extremity of the conical element.

2. A battery comprising a jar for containing an electrolyte, a lower conical element, and an upper element having a depending non-conducting stem provided with a lower connecting device to removably fit over the upper extremity of said conical element.

3. A battery comprising a jar for containing an electrolyte, a lower ointed conical copper element having a portion of the joint extended to form an elongated inclosing roll, a wire having its lower extremity held in said eaavre roll, and an upper element provided with a non-conducting device removably engaging the upper portion of said copper element.

4. A battery comprising a jar for containing an electrolyte, a lower element of hollow form having an in ner elongated tubular rolled portion, a conductor having its lower extremity held in said rolled portion, and an upper element removably applied to said lower element by an interposed non-conducting device.

5. A battery comprising a jar for containing an electrolyte, a lower copper element, and an upper zinc element'removablyattached to said lower element by an interposed non-conducting device, the said zinc element having a series of radiating wings separated by intel-spaces and provided with depending portions and upper outwardly and downwardly inclined recesses. I

In testimony that I claim the foregoing as my own I have hereto afiixed my signature in the presence of two witnesses.
